Definitions

  • the invention relates to a method of producing a detachable, anti-fouling coating, to the coating itself and to its use.
  • a need for surfaces modified in this way exists not only in the case of articles which are surrounded by atmospheric air but also, in particular, in connection with the operation of articles around the whole or part of which water passes, in order to hinder their population by aquatic organisms.
  • These articles may be, for example, walls, container surfaces, bulkheads, breakwaters, posts and other load-bearing constructions which are in long-term contact with either fresh or salt water.
  • the population pressure under water is very great. For instance, there are larvae and spores of around 6000 species of marine bionts known which settle on solid surfaces for the purpose of growing up permanently on them.
  • the secretions of the adhering organisms may promote the corrosion of the materials.
  • the contour of a ship's body is altered in such a way by the three- dimensionally projecting infestation that the flow resistance is increased by an average of around 15%, resulting in a higher fuel consumption.
  • biocidal paints are applied in order to kill or repel the larvae and spores of the unwanted organisms.
  • coatings which comprise leachable substances that are toxic to aquatic organisms.
  • Such compounds may be organic in nature, such as chlorinated aromatic hydrocarbons such as DDT, for example, or they may be inorganic in nature, such as copper oxide or copper thiocyanate, for example, or else may be organometallic compounds, such as alkyl borates or alkyltin compounds, for example .
  • a disadvantage of these prior-art biocidal paints is that the substances leached from them, over long periods of time, may contaminate the water and the sediments of the bodies of water and hence may develop unwanted harmful effects.
  • a further disadvantage is that the protective coating present must be removed at regular intervals and replaced by a new coat. This leads to disposal costs for the non-standard waste produced, to costs for the new coating material, and to labour costs.
  • the invention provides a method of producing a detachable, anti-fouling coating on an article, wherein a preparation comprising nanoscale hydrophobic particles and at least one volatile siloxane is applied to at least one surface of an article and then the volatile siloxane is removed.
  • anti-fouling means that the colonization of the article's surface by molluscs and by algae that grow to a large size is reduced or prevented entirely.
  • Volatile means that at least 95% of the siloxane has evaporated within 24 hours at 25°C.
  • Detachable means that the coating obtainable by the method of the invention can be detached from the article again by means of mechanical working such as rubbing, polishing or high-pressure water jet, yet adheres to the article during the envisaged period of use and mode of use.
  • Nanoscale metal oxide particles are understood to be those having an average diameter of 2 to 100 nm. In the case of aggregated particles, this figure relates to the primary particles present in the aggregate.
  • hydrophobic properties of the nanoscale particles may be present inherently, as for example in the case of polytetrafluoroethylene (PTFE) . It is also possible, however, to use hydrophobic particles which exhibit hydrophobic properties only after an appropriate treatment.
  • PTFE polytetrafluoroethylene
  • Nanoscale hydrophobic particles used may be silicates, minerals, metal oxide powders, metal powders, pigments and/or polymers.
  • Pyrogenically produced metal oxide particles having a BET surface area of 20 to 400 m 2 /g and in particular of 35 to 300 m 2 /g.
  • Pyrogenically produced metal oxide particles for the purposes of the invention encompass aluminium oxide, silicon dioxide, titanium dioxide and/or zinc oxide, and also mixed oxides of the aforementioned compounds.
  • pyrogenic, or fumed, metal oxide particles are meant those obtained by flame oxidation and/or flame hydrolysis.
  • oxidizable and/or hydrolysable starting materials are generally oxidized in an oxyhydrogen flame or hydrolysed.
  • Starting materials used for pyrogenic methods may include organic and inorganic substances. Particularly suitable, for example, are the readily available chlorides, such as silicon tetrachloride, aluminium chloride or titanium tetrachloride.
  • Suitable organic starting compounds may for example be alkoxides, such as Si (OC 2 H 5 ) 4 , Al (OiC 3 H 7 ) 3 or Ti(OiPr) 4 .
  • the resulting metal oxide particles are very largely pore-free and have free hydroxyl groups on the surface.
  • the pyrogenic metal oxide particles are at least partly in the form of aggregated primary particles.
  • metalloid oxides such as silicon dioxide, for example, are termed metal oxide.
  • the pyrogenic metal oxides acquire their hydrophobic properties through surface modifier reagents which react with active groups on the surface.
  • surface modifier reagents which react with active groups on the surface.
  • silanes individually or as a mixture:
  • Haloorganosilanes RX 2 Si (CH 2 ) m R'
  • Cyclic polysiloxanes D3, D4, D5 and their homologues, with D3, D4 and D5 meaning cyclic polysiloxanes having 3, 4 or 5 units of the type -O-Si (CH 3 ) 2 , e.g. octamethylcyclotetra- siloxane D4.

  • Suitable hydrophobic, pyrogenic metal oxides can be selected for example from the table of stated AEROSIL ® and AEROXIDE ® products (all from Degussa) .
  • Volatile siloxanes are all room-temperature liquid linear compounds of the general formula (I) and/or cyclic compounds of the general formula (Ia)
  • n a number from 2 to 10.

  • Cyclic and linear siloxanes can be used in a mixture .
  • the fraction of the nanoscale hydrophobic particles used in the preparation is preferably 0.5% to 15% by weight, based on the total amount of the solid and liquid constituents of the preparation.

  • the spraying of the preparation can be accomplished preferably with a pressure of 1 to 5 bar .
  • the volatile siloxane is removed by evaporation or volatilization, which can be accelerated by the use of elevated temperatures, by air movement or by the use of sub-atmospheric pressure or vacuum.
  • the method of the invention can be used to produce articles treated on at least one surface with an anti-fouling coating.
  • the article to be coated may be made, for example, of metal, plastic, wood, ceramic or glass.
  • the invention further provides a detachable, anti-fouling coating on an article, obtainable by the method of the invention .
  • One feature of the coating of the invention is that it is initially not fully wetted by water. Instead, a ternary solid/liquid/gaseous phase boundary exists. After a certain dwell time, this phase boundary undergoes transition to a fully wetted state. After that there is only a solid/liquid phase boundary. This remains in existence, even if the coated article is brought temporarily into contact with a gas phase, air for example.
  • a further feature of the coating of the invention is that it can be redetached from the article by mechanical working such as rubbing, polishing or high-pressure water jet, but otherwise adheres to the article firmly enough to maintain its service properties over a long period of several months. It is therefore especially suitable as a protective coating for articles which are maintained at periodic intervals .
  • the coating of the invention preferably has a thickness of 0.1 to 100 ⁇ m. Particular preference may be given to values of 1 ⁇ m to 50 ⁇ m.
  • the coating of the invention preferably has a concentration of the nanoscale hydrophobic particles of 0.01 to 5 g/m 2 . Particular preference may be given to values of 0.1 to 0.5 g/m 2 .
  • the invention further provides for the use of the coating of the invention for the biostatic treatment of surfaces in contact with water.
  • the invention has the advantage that articles of all kinds can be treated with an anti-fouling, physiologically unobjectionable, non-permanent coat in a simple way.
  • the coating of the invention with a detachable coat is very mild, since there is no need to use objectionable or aggressive solvents and the coating can be detached, for example, mechanically, such as by rubbing.
  • the coating produced by means of the method of the invention is non-permanent and is therefore especially suitable as a protective coating for articles that are maintained at periodic intervals.
  • Example 1 2.O g of AEROSIL R 812S are dispersed with intense stirring in 98.0 g of decamethylcyclopentasiloxane (D5) .
  • Example 2 0.5 g of siloxane wax (Tegopren ® 6814) having a molecular weight of 13 000 g/mol and a recrystallization point of ⁇ 5°C was dissolved in 97.5 g of decamethylcyclopentasiloxane (D5) . 2.0 g of AEROSIL R 812S are dispersed with intense stirring in this solution.
